IMPROVEMENT IN MACHINES FOR SLITTING AND BENDING METAL-TUBE SKELPS.

Specification forming part of Letters Patent N0. 1 11,016, dated January 17, 1871.

I, STEPHEN P. M. TAsKER, of the city of Philadelphia and State of Pennsylvania, have invented certain Improvements in Machines for Slitting and Bending Metal-Tube Skelps, of which the following is a specification:

The nature of my invention consists in the combination of a series of revolving cutters, with guides, feeding mechanism, and with the first pair of bending-rolls, as hereinafter described.

To enable others to make and use my improved machine, I will now give a full description thereof.

In the accompanying drawing, which makes a part of this specification, Figure 1 is a plan of the improved machine. Fig. 2 is a longitudinal section at the line w :c of Fig. l. Fig. 3 is a front view of the slitting device. Fig. 4 is an end view of a butt-joint skelp on an enlarged scale. Fig. 5 is a like View of the skelp in the form produced by the first pair of bending-rolls K K.

Like letters in all the igures indicate the same parts.

A is the bed-plate, and B B housings connected therewith, for the connection` of the several parts of the machine. C is a horizontal plate, connected at its ends with the housings for supporting the mouth D, through, which the sheets are passed to the feed-rolls.` E ,E E E in the said mouth D are carrying-- wheels, which facilitate the movementof the sheets.

F F are feed-rolls, geared together by means of the wheels G G on one end of the shafts b. b, for passing the sheet through the revolving cuttersH, and thence to the bending-rolls, there being guide-plates D D', the lower one being connected at its ends to the housings B B. The upper guide-plate is confined to suitable projections on the lower plate bymeans of screws d.

swer the purpose of feeding the sheet to the cutters.

The cutters H are confined on the revolving shafts I I in the frame J by means of the adjustable clamping-nuts e. The cutting device is shown in detail in Fig. 3.

K K' on the shafts II are rolls for bending the skelps as they pass from the cutters H. The bending rolls K K are connected.` by means of the gear-wheels G G. on their shafts I I. They are connected with t-he feed-rolls F F by means ofthe intermediate gear-wheel, G, on the short shaft M.

The operation is as follows: The sheet is passed through the mouth D, and is caught by the feed-rolls F F, which pass it through the revolving cutters H and bending rolls K K. As the sheet passes through the cutters its motion causes the latter to revolve in the direction of the arrow. As the skellps pass through the bending rolls K K they are brought from the flat shape represented in Fig. 4 to the form represented in Fig. 5. For giving the nishing bending tothe skelps Iemploy other rollsin connection with the rolls K. K/which IA have fully described in my specifications of other machines. I therefore deemza furtherdescription unnecessary.

I am'aware that the combination of guides, feed-rolls, andskelp-bending-rolls is not new, andI-fam alsoaware that a series of pairs of `cutting-disks forwshearing a sheet of metal into strips is not new, and I do not, therefore,

.claiinsaid devices separately; but

The combination of the series of pairs of cutting-disks with the combination of guides, feed-rolls, and skelp-bending rolls, substantially las described. i

ln testimony that the above is my invention Ibave hereunto set my hand and affixed my seal this 26th day of September, .1870.
